Management of diabetic cats with long-acting insulin.
Vet. Clin. North Am. Small Anim. Pract.
PUBLISHED: 03-26-2013
Show Abstract
Hide Abstract
This article provides an overview of the most important information regarding the long-acting insulins glargine, detemir, and protamine zinc insulin in diabetic cats. Dosing protocols are described in detail, which achieve high remission rates and optimal glycemic control. Complications and factors that typically cause insulin resistance are also examined.

Predicting interactions between T cell receptors and MHC-peptide complexes.
Mol. Immunol.

Hide Abstract
Conserved interactions between T cell receptors (TCRs) and major histocompatibility complex (MHC) proteins with bound peptide antigens are not well understood. In order to gain a better understanding of the interaction modes of human TCR variable (V) regions, we have performed a structural analysis of the TCRs bound to their MHC-peptide ligands in human, using the available structural models determined by X-ray crystallography. We identified important differences to previous studies in which such interactions were evaluated. Based on the interactions found in the actual experimental structures we developed the first rule-based approach for predicting the ability of TCR residues in the complementarity-determining region (CDR) 1, CDR2, and CDR3 loops to interact with the MHC-peptide antigen complex. Two relatively simple algorithms show good performance under cross validation.

Short communication: selection of thymidine analogue resistance mutational patterns in children infected from a common HIV type 1 subtype G source.
AIDS Res. Hum. Retroviruses

Hide Abstract
In HIV-1, thymidine analogue mutations (TAMs) cluster in one of two groups (215Y, 41L, 210W, or 215F, 219E/Q), representing two independent mutational patterns (T215Y and T215F cluster, respectively). The mechanisms by which these pathways are selected are not fully understood. To investigate possible factors driving the selection of the TAMs, we analyzed the TAM patterns with regard to the respective treatment, viral load, and HLA in 18 children all infected from a common source of HIV-1 clade G virus and initially treated with zidovudine. The HIV reverse transcriptase sequences of 14/18 children carried at least one TAM. At first sampling date, the T215Y-linked pattern was observed in five cases and the T215F cluster was seen in nine. During the follow-up period, three patients changed their patterns. Children treated with identical NRTI combinations at the first sampling date developed different pathways. Under AZT/d4T therapies, an association was found between the HLA B*13 (in combination with HLA DRB1*0701) and the mutation T215Y. The mutation T215Y reverted in three out of four patients who discontinued AZT/d4T treatment. We speculate that in the context of these subtype G viruses, the development of the T215Y mutation may be strongly disfavored whereas the presence of HLA B*13 may counteract this effect and permit its development.

Predicting MHC class I epitopes in large datasets.

Hide Abstract
Experimental screening of large sets of peptides with respect to their MHC binding capabilities is still very demanding due to the large number of possible peptide sequences and the extensive polymorphism of the MHC proteins. Therefore, there is significant interest in the development of computational methods for predicting the binding capability of peptides to MHC molecules, as a first step towards selecting peptides for actual screening.

HLA class I allele associations with HCV genetic variants in patients with chronic HCV genotypes 1a or 1b infection.

Show Abstract
Hide Abstract
The adaptive immune response against hepatitis C virus (HCV) is significantly shaped by the hosts composition of HLA-alleles with the consequence that the HLA phenotype is a critical determinant of viral evolution during adaptive immune pressure. In the present study, we aimed to identify associations of HLA class I alleles with HCV subtypes 1a and 1b genetic variants.

Intensive blood glucose control is safe and effective in diabetic cats using home monitoring and treatment with glargine.

Hide Abstract
Human diabetic patients routinely self-adjust their insulin dose using a protocol and home monitoring, and perform equally well or outperform physician directed adjustments. The objective of this study was to report the outcome of home monitoring of diabetic cats by owners using a protocol aimed at achieving euglycaemia, using ultra-low carbohydrate diets (< or =10% metabolisable energy) and the insulin analogue glargine for >10 weeks and/or until remission was achieved. Fifty-five cats diagnosed with diabetes mellitus, whose owners joined the online German Diabetes-Katzen Forum, were included. An overall remission rate of 64% was achieved in the cohort. Significantly higher remission rates were observed if good glycaemic control was achieved soon after diagnosis: 84% for cats started on the protocol within 6 months of diagnosis went into remission, and only 35% for cats that began more than 6 months after diagnosis (P<0.001). Only one mild clinical hypoglycaemic episode occurred observed despite tight blood glucose control. In conclusion, intensive blood glucose control is safe and effective in diabetic cats using home monitoring and treatment with glargine.

Evaluation of detemir in diabetic cats managed with a protocol for intensive blood glucose control.
J. Feline Med. Surg.
Show Abstract
Hide Abstract
The aim of this study was to report outcomes using detemir and a protocol aimed at intensive blood glucose control with home monitoring in diabetic cats, and to compare the results with a previous study using the same protocol with glargine. Eighteen cats diagnosed with diabetes and previously treated with other insulins were included in the study. Data was provided by owners who joined the online German Diabetes-Katzen Forum. The overall remission rate was 67%. For cats that began the protocol before or after 6 months of diagnosis, remission rates were 81% and 42%, respectively (P = 0.14). No significant differences were identified between the outcomes for the glargine and detemir studies, with the exception of three possibly interrelated factors: a slightly older median age of the detemir cohort at diabetes diagnosis, a higher rate of chronic renal disease in the detemir cohort and lower maximal dose for insulin detemir.

Gene regulatory network analysis supports inflammation as a key neurodegeneration process in prion disease.
BMC Syst Biol
Show Abstract
Hide Abstract
The activation of immune cells in the brain is believed to be one of the earliest events in prion disease development, where misfolded PrionSc protein deposits are thought to act as irritants leading to a series of events that culminate in neuronal cell dysfunction and death. The role of these events in prion disease though is still a matter of debate. To elucidate the mechanisms leading from abnormal protein deposition to neuronal injury, we have performed a detailed network analysis of genes differentially expressed in several mouse prion models.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
